JDK is a complete software development kit for developing Java applications. It comprises JRE, JavaDoc, compiler, debuggers, etc.
JRE is a software package providing Java class libraries, JVM and all the required components to run the Java applications.
JVM is a platform-dependent, abstract machine comprising of 3 specifications - document describing the JVM implementation requirements, computer program meeting the JVM requirements and instance object for executing the Java byte code and provide the runtime environment for execution.
Main Purpose
JDK is mainly used for code development and execution.
JRE is mainly used for environment creation to execute the code.
JVM provides specifications for all the implementations to JRE.
Tools provided
JDK provides tools like compiler, debuggers, etc for code development
JRE provides libraries and classes required by JVM to run the program.
JVM does not include any tools, but instead, it provides the specification for implementation.
Summary
JDK = (JRE) + Development tools
JRE = (JVM) + Libraries to execute the application
JVM = Runtime environment to execute Java byte code.
